Configuring The Mpls Control Protocol - Extreme Networks PoS Installation And User Manual

Configuring the PoS Module
When used with IPCP, the optional
provides a way to configure the IP address of the peer router. This capability is useful
with peer routers that do not advertise their IP address through the IPCP IP-Address
configuration option. If the peer router does advertise an IP address through IPCP, the
configured value for
peer-ipaddress
The following command example turns IPCP off and BCP on for port 1 of the PoS
module installed in slot 8 of the BlackDiamond switch.
config ppp ipcp off port 8:1
config ppp bcp on port 8:1

Configuring the MPLS Control Protocol

MPLSCP establishes and configures a connection for transporting MPLS labeled frames
across a PPP link. The MPLSCP connection must be established successfully before
MPLS labeled data traffic can flow over the link. Only unicast MPLS labeled packets are
supported. Multicast MPLS labeled packets are discarded by the PoS port.
MPLSCP is not explicitly configured on a PoS port. However, MPLSCP is automatically
enabled on a PoS port when the port is configured for IPCP and MPLS is enabled on
the VLAN that the PoS port is a member of. When MPLSCP is enabled on a PoS port,
the port will transport IP and MPLS labeled packets, and the port must be a member of
one and only one VLAN. Furthermore, no other ports may be members of this VLAN,
and IP routing is the only protocol supported on the VLAN. The one exception to this
rule occurs when APS is enabled. A single VLAN may contain two IPCP-enabled ports
if they are members of the same APS group.
You must have a PoS module and an MPLS module installed in your
BlackDiamond switch to use MPLS on a PoS port.
To configure MPLSCP on a PoS port, complete the following steps:
1 Create a VLAN for the PoS port using the
2 Add the PoS port to the VLAN using the
command.
3 Define an IP router port on the VLAN by assigning an IP address to the VLAN
using the
config vlan <name> ipaddress <ipaddress> {<mask>}
4 Disable BCP on the PoS port using the
command and enable IPCP on the PoS port using the
command.
